Sr20 Swap Into A R32 Shell

[mad082]

i just did a little looking at specs. something else you may want to think about is that the silvia has a slightly wider front track than a 32, has lower and skinnier body (so it MAY have less drag at speed).

also 20kg may not seem like a big difference in weight, but in a lower power vehicle it can be enough over a few laps to determine what position you are in.

the track issue is easily fixed, same as we do on S series chassis.... by fitting R33 lower control arms (among other things).

Nah sorry i build a few CA's and alot of Sr's. I dropped the latest CA build to Drift garage/UPgarage in nsw last week and i cannot lift the 'long' CA at all.... the SR on the other hand i can manouver around my workshop my self.

the 26 in our s13 puts about 30-45kg more over the front axle.

What does the CA weigh then? What does the SR weigh? Provided their accessories are identical, and do not have transmissions.

I got my information from a pretty reliable source. I do not have proof, but neither do you..

Could you get both motors on a scale to confirm?

mate if i can lift one but not the other then they weigh differrent...... proof enough for me. (long bare engines, maybe loaded with access they are heavier)

if anyone needs a newly built 300rwkw CA (long motor) i have a spare one... oh and a fully built SR filled with Trust cams, rods and pistons out of cats car (just had re-fresh) and a Forged (arias) SR20 also fresh.

on the scales at drift day

S13 Sr20 manual turbo 1200kg average

R32 rb20 turbo manual 1320 avrage

S13 Rb20 manual turbo 1260kg

R32 with Sr20 1260

Note CA S13 was definetly lower then SR, i dunno if thats the body(88 - 91 car) or what but they where around 1160 kg.

I would say 60kg between SR and RB20 including manifolds(yes 6 has heavier everything) and gearbox(sr / rb20 same same).

Fully stripped out Silvias got down to 1040 kg for interest sake

yeah you are comparing cars not engines..... our s13 weighed 1100 with sr last year at EC.... and 1200 with rb... but the engine is not 100kg heavier. The CA cars do weigh less maily due to equipment not engines. Hicas / non hicas, sunroof etc all play a part.

Did i say i was comparing anything other then cars ?

the CA S13 car has all the same features as An SR one I think ?

so not sure where the extra car weight comes from.

ca18det engine only = 128kg

sr20de engine only = 139kg

sr20det engine only = 149kg

don't know what accessories are included in those weights.
